Abstract (en)
[origin: EP1349116A1] The process is characterized in that it comprises, for validating the model, the following steps: predetermination of a maximum permitted distortion (5) on a 2D synthesized image (4), generated by the approximation inherent in the model (2), calculation, for a point I of a reference image (7) and on a set of synthesized images (4) representing the 3D point of the scene corresponding to this point I, of the minimum (zi - DELTA zi<1>) and maximum (zi + DELTA zi<2>) depth values of the depth zi of this point I corresponding to this maximum distortion, calculation of a span around the depth zi of this point I, dependant on the minimum value of the error DELTA zi<2> and on the minimum value of the error DELTA zi<1> among the values calculated for the synthesized images of the set. <??>Applications relate to the construction of models for the synthesization of images or the compression of data. <IMAGE>
